WATER-CLOSET.-

SPECIFICATION forming part of Letters Eatent No. 708,106, dated September 2, 1902. Application led January l3,`1902. Serial No. 89,417. (No model.)

To all whom, t may concern.-

Be it known that I, FRANK A.' WELLS, a citizen of the United States, and a resident of New York city, borough ofManhattan, State of New York, have invented certain new and useful Improvements inWater-Closets, of which the following is a specification.

The objects of my invention are to provide improved means to prevent siphoning when 1o a volume of water is poured into the bowl of the closet and to assist the proper siphoning and at the same time to prevent gases rising from the soil-pipe from passing into the room; and to these ends my invention contemplates I5 the novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein- 2o Figure 1 is a vertical section of a water! closet embodying my improvements, taken substantially on the line 1 1 in Fig; 2; and

Fig. 2 is an end View thereof, partly in section, substantially on the plane of the line 2 2 in Fig. 1.

In the accompanying drawings, in which similar numerals of reference indicate corresponding parts in the several views, the numeral 1 indicates the bowl of a water-closet,

3o which may be made in well-known manner,

2 being the upward soil passage or leg leading from the bowl, and 3 the down leg or passage, which legs communicate above the water-line, as at 2a. In the example shown these legs or passages are of the class placed side by side transversely of the bowl in well-known manner, although they may be otherwise arranged. The down-leg 3 connects with a soil leg or outlet 3a, being suitably formed to pro- 4o vide a lower water-pocket 4. Extending upwardly along the wall of the bowl is an upjet duct 5', which passes under the bowl and is provided with a jet-opening 5a, located in position to direct a jet of water into the upward passage or leg 2, and the duct 5 at its upper end communicates with an opening 6 to receive a supply of water, from which supply the iiush-rim 7 may also be supplied, as indicated in Fig. l; but the water-supply 5o maybe otherwise arranged.

8 indicates adown-jet duct whose lower\ end projects into the duct 5 at a distance below the normal water-level in the bowl, and the upper end of the duct 8 communicates through an opening 8a with the upper part 55 or crown of the down passage or leg 3, whereby when water ills the down-duct 5 it will rise back through the duct 8 and pour through the opening 8a into the down-leg 3 in the form of a jet and the water from the duct 5 will 6o also pass up through the opening 5a into the up-leg 2 to force waterfrom the bowl over the edge 2b in well-known manner. x

The above-described parts are illustrated for use in connection with my improvements and may be, altered from the construction shown, if desired.

From the upper part or crown of the soil passage or leg 3n extends a duct 9, which opens through the wall of said leg, as indicated at 7o OfL in Fig. 1, and said duct 9 passes thence upwardly and opens into the duct 8, as through an opening 10, above the normal level of the water in the bowl and in such position that when water rises up in the duct 8 from the 75 duct 5 it will ow through the opening 10 down through duct 9 and thence into the soil passage or leg A3% In Fig. 1 the far wall of the bowl 1 is broken away to disclose the connection of the duct 9 with the top or crown of 8o the soil down-leg 3a. The duct 9 may be applied and carried between the openings 9a and 10 in any suitable or well-known manner. I It will be understood that gases that would rise through the leg 3 are trapped by the wa- 8 5 ter in the bowl, that the water in the duct 5 traps the duct 8, and that gases that would rise from the leg 3y through duct 9 are also trapped by the water in the bowl and in the duct 5. go

With my improvements if a volume of water is dumped into the bowl it is prevented from siphoning the bowl because of the air supplied by the duct 9 from the soil-leg 3a through the openings 10 8*, leading to the'water-space 9 5 in the leg or passage 2, so that when water is thus poured into the bowl it will merely flow over the edge 2b, leaving substantially the normal water-level in the bowl. Furthermore, when the bowl is to be emptied in the los as fast as it enters duct it backs up through duct 8 and produces a jet through the opening 8, directed into the down-leg 3 to assist the siphoning, and the water also at such time passes through the opening 10 into duct 9 aud pours down through opening 9a into the down-leg 3, assisting in sucking air out of the leg 3, and thereby helping the siphoning action.

Having now described my invention, what I claim isl. A water-closet provided with a bowl and up and down communicating passages orlegs, a soil-leg communicating with the down-leg, aductcommunicatingwithajet-openingleading to the bowl, and a duct communicating with the soil-leg below the level of the water in the bowl and with the first-mentioned duet, and also with said passages or legs above the normal level of the water in the bowl, substantially as described.

2. A water-closet provided with a bowl and up and down com mu nicating passages or legs, a soil-leg communicating with the down-leg, a duct communicating with a jet-opening leading to the bowl, the down-leg having an upper jet-opening communicating by a duct with the first-mentioned duct, and a duct communicating above the level of the water in the bowl with the second mentioned duct and said passages and also with the soil-leg, substantially as described.

3. A water-closet provided with a bowl and up and down communicating passages or legs, the down-leg having a water-pocket and communicating with a soil-leg, a duct communieating with a jet-opening leading to the bowl, a duct communicating with said duct below the normal water-level in the bowl and also communicating with the down-leg above said water-level, and a duct communicating With the soil-leg above said pocket and also communicating with the second-mentioned duct and with said passages above the normal level of the water in the bowl, substantially as described.
